CHARLES ASHTON HENR Y B'ULLOCK,V OF LONDON, ENGLA NID TYPESETTING-APPARATUS.

Application filed May 26, 1923. Serial No. 641,734.

To all whom it may concern:

Be it known that I, CHARLES AsHToN HENRY BULLOCK, a subject of the Kingof Great Britain, and a resident ofLondon, England, have invented acertain new and useful Improvement in Typesetting Appa ratus, of which.the following is a. specifica tion. i

This invention relates to type setting apparatus of the kind describedin the specification of my prior application Ser. No. 539,536 and inparticular to the type ejecting units therein employed.

In apparatus of the above type the type is stored in stationary channelsarranged at such an angle that the type gravitates to the lower ends ofthe channels at which ends are placed the type ejecting units. Each ofthese units operates to eject a single piece of type by the depressionof a key.

One of the objects of the present invention is to reduce frictionbetween the piece of type to be abstracted and the rest of the typewithin the channel.

In practice it is found that the weight of a channel full of type makesthe removal of a single piece from the lower end of the channel adifficult process. This defect is removed accordingto this invention byraising the piece of type to be removed to a position where it is almostclear of the rest of the type in the channel such elevation of a pieceof type taking place automatically after each removal of a previouslyraised piece of type. The present invention consists broadly of a. typeejecting unit for use in connection with a type setting apparatus havingstationary channels wherein the type is stored in which the piece oftype to be abstracted remains stationary during the depression of aspring supported plunger which serves upon depression to lower one ormore of the adjacent pieces of type which were raised during theprevious operation of the plunger.

A type ejecting unit according to the preferred form of the inventioncomprises a spring supported plunger provided with a platform whichmoves with it and serves to collect two or more pieces of type whendepressed and raise the same to an elevated position when released, andmeans such as a fixed projection or platform for maintaining a singlepiece of type in such elevated position during each depression of theplunger whereby the same is maintained in a position from which it maybe readily abstracted.

In order that the invention may be clearly understood an embodiment ofthe same will now be described by aid of the accompanying drawings inwhich Fig. l is a diagrammatic perspective view of a. typesetting frameshowing units ac cording 'to this invention in position in the typechannel.

Fig. 2 is a fragmentary perspective to an enlarged scale of one of thechannels and an ejecting unit in position therein.

Fig. 3 is a part sectional elevation of the unit and channel showing twopieces of type in the elevated position and the plunger of the unit inits raised or normal position.

Fig. A is a similar view but showing the plun 'er of the unit depressedand a single piece of type in position for abstraction.

Fig. 5 is an underside plan view of a portion of one of the channelsshowing the apertures for the units and the means for securing the sidesof the channels to the base.

The typesetting frame shown in Fig. 1 comprises a rectangular frame 1which is supported at an angle by means of legs 2, the inside of theframe being composed of a plurality of parallel channels 3 in which theunits f according to this invention are detachably secured.

A type ejecting unit according to the form of the invention showncomprises a casing 5 which is adapted to project through a slot 6 in thebottom of the channel in which the type 7 is stored, a pair of sideflanges 8 at its upper end serving to support the same by engagementwith the top edges of the sides of the channel. In this position thecasing is secured by means of a nut 9 and a. U washer or saddle 10disposed beneath the bottom of the channel. A spring supported plunger11 is slidably mounted in this casing and such plunger is formed with aplatform or lateral projection 12 which extends through a slot 13 in theside of the casing which opposes the type in the channel. The upper edgeof this platform is above the bottom of the channel when the plunger isin its normal position.

hen the plunger is depressed however this upper edge sinks to a positionflush with or slightly below the bottom of the channel in which positionthe adjacent pieces of type move thereover under gravity so that whenthe plunger is released such pieces of type resting on the platform areraised These lips are of such a size as toengage a' single piece of typeonly upon each depression of the plunger thus serving to hold such pieceof type stationary when the plunger is depressed The upper end otftheplunger is provided wlth a key or finger piece 15 havmgan opening 16therein through whichthe single supported piece of type projects whenthe plunger is depressed. This piece of type may thus be grasped by theoperators fingers simultaneously with the depression of the'plungerwhich is elfected by the same medium.

-lVl1at I claim and desire to secure by Letters Patent is A typeejectingunit for use in connection with a type setting apparatus havingstationary channels comprising a spring supported plunger provided witha platform which moves with it and serves to collect more than one pieceof type when depressed and raise the same to an elevated position whenreleased and means such as a fixed pr0 ect10n for maintaining asmglepiece of type in such elevated position during each K depression of theplunger whereby the same is maintained in a position from which it
